Why do I receive following compiler warning:
Incompatible pointer types sending 'NSManagedObject *' to parameter of type 'ToDoItem *'
at the last line of this method?:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSManagedObject *object = [[self fetchedResultsController] objectAtIndexPath:indexPath];
self.detailViewController.editToDoItem = object;
}
ToDoItem is a NSManagedObject subclass.
self.detailViewController.editToDoItem
expects a ToDoItem
object, so you cannot pass an object of the NSManagedObject
superclass :
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ToDoItem *object = [[self fetchedResultsController] objectAtIndexPath:indexPath];
self.detailViewController.editToDoItem = object;
}
